The attention mechanism can highlight fine-grained features with critical information, thus ensuring that feature extraction emphasizes the objects related to the questions. However, unattended coarse-grained information is also essential for questions involving global elements. We believe that global coarse-grained information and local fine-grained information can complement each other to provide richer comprehensive information. In this paper, we propose a dual capsule attention mask network with mutual learning for VQA. Specifically, it contains two branches processing coarse-grained features and fine-grained features, respectively. We also design a novel stackable dual capsule attention module to fuse features and locate evidence. The two branches are combined to make final predictions for VQA. Experimental results show that our method outperforms the baselines in terms of VQA performance and interpretability and achieves new SOTA performance on the VQA-v2 dataset. %U https://aclanthology.org/2022.coling-1.500 %P 5678-5688
